Question 932127: the length of a rectangular room is three less than twice its width. Find the dimensions of the perimeter is 54 ft. Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! L = 2w - 3
2L + 2w = 54
---
2L + 2w = 54
2(2w - 3) + 2w = 54
4w - 6 + 2w = 54
6w = 60
w = 10
L = 2w - 3
L = 2*10 - 3
L = 23
---
L = 23 ft
w = 10 ft
